A simple, lightweight distribution

You've reached the website for Arch Linux, a
lightweight and flexible Linux® distribution that tries to Keep It
Simple.

Currently we have official packages optimized for the x86-64
architecture. We complement our official package sets with a
community-operated package repository that grows in size and
quality each and every day.

Our strong community is diverse and helpful, and we pride ourselves
on the range of skillsets and uses for Arch that stem from it. Please
check out our forums
and mailing lists
to get your feet wet. Also glance through our wiki
if you want to learn more about Arch.

The zita-resampler 1.6.0-1 package was missing a library symlink that has been readded in 1.6.0-2. If you installed 1.6.0-1, ldconfig would have created this symlink at install time, and it will conflict with the one included in 1.6.0-2. In that case, remove /usr/lib/libzita-resampler.so.1 manually before updating.

Following 9 months of deprecation period, support for the i686
architecture effectively ends today. By the end of November, i686
packages will be removed from our mirrors and later from the packages
archive. The [multilib] repository is not affected.

For users unable to upgrade their hardware to x86_64, an alternative is
a community maintained fork named Arch Linux 32. See their website
for details on migrating existing installations.

The perl package now uses a versioned path for compiled modules. This means
that modules built for a non-matching perl version will not be loaded any more
and must be rebuilt.

A pacman hook warns about affected modules during the upgrade by showing output
like this:

WARNING: '/usr/lib/perl5/vendor_perl' contains data from at least 143 packages which will NOT be used by the installed perl interpreter.
-> Run the following command to get a list of affected packages: pacman -Qqo '/usr/lib/perl5/vendor_perl'

You must rebuild all affected packages against the new perl package before you
can ...

Due to high maintenance cost of scripts related to the Arch Build
System, we have decided to deprecate the abs tool and thus rsync
as a way of obtaining PKGBUILDs.

The asp tool, available in [extra], provides similar functionality to
abs. asp export pkgname can be used as direct alternative; more
information about its usage can be found in the documentation.
Additionally Subversion sparse checkouts, as described here, can
be used to achieve a similar effect. For fetching all PKGBUILDs, the
best way is cloning the svntogit mirrors.

While the extra/abs package has been already dropped, the rsync
endpoint ...
